Discover UChicago
The University of Chicago is now accepting applications for the Discover UChicago program, an expenses-paid weekend visit to be held October 20-22, 2016, for candidates traditionally underrepresented in their fields who are planning to apply to graduate school in the fall of 2016. This exciting event combines workshops on applying to graduate school, individual meetings with faculty, and opportunities to connect with current Chicago students, as well as to explore the area. In particular, students from underrepresented backgrounds, first generation students, and women in STEM fields are invited to apply. A full list of participating programs, as well as application requirements and additional guidance, may be found at grad.uchicago.edu/admissions/discover/. Any questions may be directed to gradadmissions@uchicago.edu. Application deadline: August 15, 2016.

Iron, Cobalt and Nickel Complexes as Responsive MRI Contrast Agents
Unpaired electrons of metal ion coordination complexes influence both the chemical shift and the relaxation time of neighboring protons. Paramagnetic properties of these metal ion complexes induce a change in the water proton signal to produce magnetic resonance imaging (MRI) contrast. Paramagnetic complexes of first row transition metal ions are under development as MRI contrast agents as alternatives to the clinically used gadolinium agents. The coordination chemistry of transition metal ion complexes is more versatile than that of lanthanides complexes and may be used to switch on and off contrast with changes in biological pH, temperature or redox environment. In our group, we have prepared macrocyclic complexes of Fe(II)/Fe(III), Co(II)/Co(III) and Ni(II) with the goal of controlling oxidation state, spin state, geometry and complex rigidity. These complexes function through paraCEST (paramagnetic chemical exchange saturation transfer) to produce contrast. The potential of “smart” transition metal ion MRI contrast agents for applications in biomedicine will be discussed.
Journal Club Meets This Week
Journal Club meets this Thursday at noon in Mudd 171 to have lunch and discuss a paper relating to this week’s seminar. Go to the following for information about what to read beforehand: http://apps.carleton.edu/curricular/chem/events/?category=171005&no_search=1.
Lunch with Seminar Speaker
Lunch with this week’s seminar speaker will be Friday, 12:00-1:00 p.m., in the LDC Class of ’51 Dining Room. Meet in the hallway outside Steve Drew’s office. If you are off board, the department will cover your lunch.
Australia Ecology Program – Deadline Extended
The application deadline for the Winter 2017 Carleton Australia Ecology Program has been extended until April 25. The program prerequisite is one biology class at Carleton or an equivalent. There will not be a Carleton biology program offered in the winter of 2018. If you have any questions, please contact Professor Bosacker at albosack@carleton.edu.
